Weathering performance of particleboards manufactured from blends of forest residues with Red pine (Pinus brutia) wood

Red pine cone and barks combined with red pine wood particles in various proportions were used as the raw materials for one and three layered experimental particleboard manufacturing in laboratory conditions. The pine cones and barks have higher lignin, but lower holocellulose content compare to woo...
